Handheld smart meter carrier module detection apparatus

Abstract

A handheld smart meter carrier module detection apparatus belongs to the technical field of electric power system detection, operation, and maintenance, including a chassis. A battery power supply system, a liquid crystal display module, a keyboard input module, a storage module, a clock unit, a power monitoring unit, a status parameter output unit, a direct current inversion alternating current module, a narrowband / wideband signal simulator, a signal modem module, and a core module are disposed inside the chassis. A liquid crystal display, a power switch, an alarm light, a frequency modulation knob, an adjustment key, a keyboard interface, and a power interface are disposed on the chassis. The invention uses a handheld and convenient structural design concept, maximizes a structural improvement, and rationally uses each inch of internal space. The detection apparatus can cover a fullband and effectively improve work efficiency, is portable, secure, and simple to operate, and can prevent a potential safety hazard of hot-line work.

Description

technical field [0001] The invention belongs to the technical field of power system detection, operation and maintenance, and in particular relates to a hand-held smart meter carrier module detection device capable of fully covering the carrier module types at the same time. Background technique [0002] With the continuous advancement of smart grid and ubiquitous power Internet of Things construction projects, smart meters, as a part of smart grid and power Internet of Things terminals, transmit data through power lines. An important part of networking. The carrier communication module is an important part of the smart energy meter. When the carrier communication module fails, it will directly affect the uploading of data collected by the smart energy meter. When collecting and maintaining personnel to judge whether the communication of the carrier communication module is normal, a professional detection device is required, but the existing detection device is bulky, incon...
